Chart Work

• Lines of Position & GC sailing
• Piloting
• SAR search patterns

Using the GPX utility and the Chart Work family of programs is it possible to do on an electronic nautical chart the work you do in a traditional way.
The three programs are:

1. Lines of position and Great Circle sailings (orthodromic).
2. Piloting: Currents and coastal fix.
3. Search & Rescue search patterns.

GPX output includes:

Coastal navigation LoP

• Bearing
• Range
• Horizontal angle

Celestial navigation LoP

• Marcq St. Hilaire Line of Position
• Circle of Position

Radionavigation LoP

• RDF bearing

Route

• Great Circle
• Composite

Piloting and coastal fix

• Currents Drift and Set
• Lasheras
• Ciclonic method
• Fix by simultaneous Distance and Bearing of same object. Geographic Range, D( waterline, top of object )
• Fix by 2 simultaneous Horizontal Angles

SAR search patterns – Patrones de búsqueda SAR

• Expanding Square
• Sector Search
• Parallel Search for one ship
